As stated in the intro photosynthesis, “is the process is where plants use “light energy from the sun that is converted into carbon dioxide and water to glucose sugar and oxygen gas through a series of reactions.” ("Chemical Formula Basic Chemistry - Writing Chemical Formula To Balancing Chemical Equations", 2014) All of this information is complied in an equation that helps understand the process, carbon dioxide + water = light energy => glucose + oxygen. The carbon dioxide can be found in the air, water comes from the earth and the energy comes from the sun. Chloroplasts trap the light energy, water then enters the leaves from the earth, and the carbon dioxide enters from the stomata. All of these combined produce glucose and oxygen, which then leaves the leaf and is stored in the plant tissue.…
Photosynthesis is the process in which light energy is converted to chemical energy, and allows plants to grow, flower and produce seed. The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll The energy of the light is absorbed by chlorophyll and in turn supplies the plant with energy to transform carbon dioxide and water into oxygen and carbohydrates. (lab handout). The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll.…
Photosynthesis is the process by which green plants, algae and some bacteria absorb light energy and use it to synthesize organic compounds. In green plants, photosynthesis occurs in chloroplasts, that contain the photosynthetic pigments. Photosynthesis occurs by slightly different processes in C3 and C4 plants. Factors which can affect this are the stomata. Plants can regulate the movements of water vapor, O2 and CO2 through the leaf surface. This is accomplished by opening and closing the stomata, usually found on the bottom…
| oxygen is absorbed into plant leaves to create chlorophyll, which is converted to glucose.…
Photosynthesis is a chemical process that converts the sunlight into a chemical energy that plants store for later. Without photosynthesis, the world as we know it would not exist. All the plants would die and so would a major food and oxygen source. During Photosynthesis water is sucked up through the roots up the stem and to the leaves. The leaves take in carbon dioxide and begin to absorb sunlight. these things combine to make glucose and oxygen. The plant then uses the glucose and oxygen is expelled through the stomata of the plant as a waste product. In The leaves there are a very special pigment called chlorophyll. Chlorophyll is responsible for the absorption of sunlight. Richard Martin Willstätter is the man responsible for studying these structures.…
Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At three minutes into the trial the student recorded that no leaf disks had still yet to rise to the top of the solution.…
1. Would you illuminate your house plants with a green light bulb? Why or why not?…
It is common knowledge that plants need light to grow and develop. This is done by the conversion of light energy into usable sugars during photosynthesis. Light absorbing molecules, known as pigments, absorb only specific wavelengths of visible light, mostly blue and red wavelengths (1). Whatever wavelength isn’t absorbed is reflected and the reflection is the color of plant we see. Plants also respond to wavelengths of light in non-photosynthetic related responses allowing them to adjust to their environment for optimal growth and development.…
Photosynthesis is the process by which plants and some other organisms convert solar energy to chemical energy in the form of sugars. In this reaction, the energy from sunlight is harnessed and utilized to form sugar molecules from carbon dioxide and water, forming oxygen gas as a byproduct.…
Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place, the effect of chlorine in the presence of photosynthesis reactions were studied. Elodea was inserted into different beakers. One containing water and the other, bleach. The elodea was left unattended for an hour so that observations could be made to tell the difference in the results each beaker produced. After an hour the quantity of CO2 present was measured for the beaker with water and the beaker containing bleach. The results recorded were inconclusive because the bleach had a buffer that evidently lowered the pH, the beaker that had water in it showed signs that photosynthesis had transpired.…
This experiment focuses on the effect of light intensity on the rate of photosynthesis. In simple terms this refers to how the production rate of the products of photosynthesis (oxygen and glucose) will be affected by a light source at different distances. The hypothesis states that “If there is a higher light intensity, then more oxygen and glucose molecules will be produced, and the rate of photosynthesis will increase.” This hypothesis was accepted. This was determined by counting the number of oxygen bubbles produced by the plant in three minute time periods, while placing the plant at three separate distances from the light source.…
Photosynthesis is an amazing process where plants are able to create their own food as well as oxygen using sunlight, carbon dioxide (co2), and water. The part of the plant responsible for photosynthesis is the enzymes in the chlorophyll (structures that carry out photosynthesis located in leaves). Photosynthesis is the process of creating glucose. Water + Carbon Dioxide + Sunlight = Glucose + Oxygen. There are three main factors that can influence the rate of photosynthesis-- temperature, carbon dioxide levels and light. If one of these factors is not present or in insufficient quantities, photosynthesis cannot occur.…
The reason for the experiment is to see which color from the light spectrum causes plants to grow faster. The prediction was that read light would cause the most growth in plants and that blue light would result in slower growth. The results did not support the hypothesis. Referring to table, one can see that blue caused both the spinach and radish plant to grow the most and that green light cause the plants to grow less.…
In photosynthesis a plant takes in carbon dioxide, water, and sunlight to produce its food and energy. The sun puts off wavelengths that allow plants to capture photons. To a plant photosynthesis is a process that produces sugars called glucose and fructose then the plant uses the sugars as food. To a human the process recycles carbon dioxide into oxygen for us to breath. The plants surroundings are where it acquires everything it needs for photosynthesis. It absorbs sunlight through its leaves as well as water through its roots. All plants have tiny vents called stoma, which allows gases like CO2 and water to pass through.…
Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. Plants need water, Co2 and light energy to create sugar. Photosynthesis occurs mainly in leaves and in 2 phases: light reaction and dark reaction. The light reactions converts light energy to chemical (Biology.clc.uc.edu, 2014). This chemical reaction must take place in the thylakoid membrane. Chlorophyll (the green pigment involved in photosynthesis) and several other pigments are organised in clusters in the above membrane (Bailey, 2014). Each of these pigments are differently coloured and can absorb a slightly different colour of light and pass its energy to the central chlorophyll molecule to do photosynthesis.…
